A member asked:

What are some medical problems that would cause a child to cough up blood?

A doctor has provided 1 answer

Nose bleed: The most common reason would be a nose bleed causing blood to be swallowed. One needs to be concerned about a foreign body which may have been inhaled. There are a number of rare congenital abnormalities or lung problems that would entail a full pulmonary work-up but these are extremely unusual.
